Spain: 3 New AVE High-Speed Rail Lines in 2026 and How Rail Liberalization Is Slashing Prices

Renfe, Ouigo, iryo: the trio that transformed Spain’s rail landscape

In barely four years, Spain has become the world’s textbook case for high-speed rail liberalisation. According to RailTech, the Madrid–Barcelona route — the country’s busiest — has seen average prices fall by 58% compared to the Renfe monopoly era. The trigger: the arrival of Ouigo España (a subsidiary of SNCF Voyageurs) in May 2021, followed by iryo — a joint venture between Trenitalia (51%), Air Nostrum (25%), and Globalvia (24%) — in November 2022.

The figures from the CNMC (National Commission for Markets and Competition) speak for themselves: between 2019 and 2024, the number of high-speed passengers grew by 77.2%, an additional 17.2 million travellers per year. Ouigo alone has carried nearly 20 million passengers in Spain since its launch. The average fare reduction across all corridors is estimated at 40%.

The fare war sometimes reaches unprecedented levels. During flash sales, Ouigo and Avlo (Renfe’s low-cost brand) offer tickets at 1 euro on Madrid–Barcelona or Madrid–Valencia. Even outside promotions, it is common to find journeys at 7, 9, or 15 euros between two major Spanish cities — prices comparable to carpooling, but for a trip at 300 km/h. According to Equinox Magazine, this competition has triggered a massive modal shift from planes to trains on the served corridors.

The three operators you need to know

• Renfe (AVE / Avlo): the historic operator with the most extensive network. Avlo is its low-cost brand with tickets from 7 €.
• Ouigo España: SNCF subsidiary, double-decker trains, tickets from 1 € in flash sales. Madrid–Barcelona, Madrid–Valencia, Madrid–Alicante.
• iryo: Italian-Spanish alliance, Frecciarossa 1000 trains, premium comfort at competitive prices. Madrid–Barcelona, Madrid–Seville, Madrid–Málaga.
• Phase 2 of liberalisation: opening of the Madrid–Galicia, Madrid–Asturias/Cantabria, and Madrid–Cádiz/Huelva corridors to competition.

200 km of new track connecting Almería to the high-speed network

The Mediterranean Corridor is Spain’s largest railway construction project — and one of the most eagerly awaited in Europe. This section between Murcia and Almería, approximately 200 km of new track, is the missing piece that will finally link the Spanish Mediterranean coast in a single stretch, from the French border all the way to eastern Andalusia. According to ADIF Alta Velocidad, Spain’s railway infrastructure operator, construction was 65% complete as of August 2024.

The inauguration of this section is planned for 2026, although the delays accumulated by the broader Mediterranean Corridor project call for caution. According to Maldita.es, the complete corridor will not be fully operational until 2027–2028. However, the Murcia–Almería section is a national priority and benefits from European funding through the NextGenerationEU programme.

For travellers, the impact will be considerable. Almería, until now one of the most poorly connected provincial capitals in Spain, will finally be linked to the AVE network. Journey times to Madrid, Barcelona, and Valencia will be reduced by approximately 30%. The corridor will also open new possibilities for coastal tourism along the Costa Cálida and the Costa de Almería, two areas still relatively untouched by mass tourism.

What this line changes for travellers

• Almería finally connected to the national high-speed network
• Murcia–Almería in 1 hour instead of 2h30 on the current regional train
• Continuous Mediterranean Corridor from Barcelona to Almería by high-speed rail
• Easier access to the beaches of the Costa de Almería and Cabo de Gata Natural Park

A journey cut by three thanks to new infrastructure

Connecting Alicante to Valencia in 50 minutes instead of 2h15: that is the promise of the new high-speed section set to enter service in 2026. This section, part of the broader Mediterranean Corridor project, will radically transform mobility between the two main cities of the Valencian Community. With trains capable of reaching 300 km/h, what was once a regional journey becomes a commuter trip.

The impact on daily life will be major. According to Le Petit Journal, this fast connection could create a truly integrated living area between Alicante and Valencia, similar to what the Madrid–Toledo line (33 minutes) has achieved in Castile. French expatriates on the Costa Blanca — one of the largest French-speaking communities in Spain — see it as an opportunity for easier access to Valencia’s international airport and its high-speed rail station.

For tourists, this change opens up unprecedented combined itineraries. You could visit Valencia in the morning (City of Arts and Sciences, Central Market, old town) and be in Alicante for lunch by the sea, or the other way around. With competition between Renfe, Ouigo, and iryo on this corridor, prices are expected to remain particularly aggressive — potentially under 10 euros for a 50-minute high-speed journey.

Why this line is a game changer

• Journey time cut by three: from 2h15 to 50 minutes between Alicante and Valencia
• Tourist combinations: Valencia + Alicante + Costa Blanca in a single trip
• Low-cost fares expected: prices estimated under 10 € thanks to competition
• European connection: eventually, Barcelona–Alicante non-stop via the Mediterranean Corridor

3h30 and from 29 €: Renfe crosses the Pyrenees

This is the rail event that concretely brings France and Spain closer together. Since the second quarter of 2025, Renfe has operated a direct service between Toulouse and Barcelona in 3h30, with stops at Carcassonne, Perpignan, Figueres, and Girona. According to the official Renfe press release, tickets start at 29 euros — a fare that defies all competition from planes or cars.

This service is a boon for southern France. Toulouse, France’s fourth-largest city, had no direct high-speed rail link to Barcelona until now. The car journey takes around 3h30 to 4 hours (without traffic), the budget bus 5 to 6 hours, and flying — including airport transfers — barely less than 3 hours in total. The Renfe train, departing from the centre of Toulouse and arriving in the centre of Barcelona, offers the best time-price-comfort compromise.

Beyond Toulouse, the whole Occitanie region benefits from this opening. The intermediate stops at Carcassonne and Perpignan allow residents of these cities to reach Barcelona without a car, while the stops at Figueres (Dalí Museum) and Girona (cathedral, Jewish quarter, Michelin-starred dining) make it a powerful tourism tool. According to Le Petit Journal, Renfe plans to eventually connect this line to the rest of the Spanish AVE network, opening the prospect of a Toulouse–Madrid journey by train with a short connection in Barcelona.

What this line offers travellers

• Toulouse–Barcelona in 3h30, city centre to city centre, no transfer needed
• Tickets from 29 €: cheaper than budget flights with luggage
• 4 tourist stopovers: Carcassonne, Perpignan, Figueres (Dalí), Girona
• AVE connections from Barcelona to Madrid, Seville, Málaga, and the entire Spanish network
• Reduced carbon footprint: 50 times less CO₂ than flying on this route

Comparison table: where to find the best fares

The great strength of the Spanish system is direct competition on the same lines. On the Madrid–Barcelona corridor, you can choose between Renfe AVE (premium), Avlo (Renfe low-cost), Ouigo España, and iryo. Prices fluctuate depending on the operator, date, and occupancy. Here is a comparison table based on fares observed in March 2026, compiled from data by RailTech and our own research on operator websites.
